brake.– Pull switch ⇒fig. 136 to apply the parking brake. The
indicator lamp in the switch will light up.
– Depress the brake or accelerator pedal and press the
switch at the same time to release the parking brake. The
indicator lamp in the switch will go out.Your vehicle is equipped with an electro-mechanical parking brake.
The parking brake replaces the conventional handbrake, and is
mainly intended to prevent the vehicle from rolling away acciden-
tally.
However, the electro-mechanical parking brake also offers a number
of convenience and safety features in addition to the functions of a
normal handbrake.When driving away
•
The parking brake auto release function releases the parking
brake automatically when you wish to start moving ⇒page 122,
“Driving away from a standstill”.
•
When driving away on a gradient, the parking brake auto release
function prevents the vehicle from rolling back unintentionally. The
braking force of the parking brake is only released when there is
enough power at the wheels to make the vehicle move in the desired
direction.
Emergency braking function
An emergency braking function enables you to stop the vehicle even
if the conventional foot brake should fail to work ⇒page 123,
“Emergency braking function”.

Technical data braking force of the parking brake is only released when there is
enough power at the wheels to make the vehicle move in the desired
direction.
Note
For safety reasons the parking brake will only release automatically
if the driver's seat belt is engaged in its buckle.Driving away when towing a trailer
Please note the following points to prevent the vehicle
from rolling back unintentionally on a gradient.– Pull and hold the parking brake switch and press the
accelerator. The parking brake will remain engaged and
prevent any tendency to roll back down the slope.
– You can release the parking brake switch as soon as the
engine is delivering enough power to the wheels.Depending on the weight of the vehicle and trailer and the steep-
ness of the slope, there may be a tendency to roll back downhill
when driving away from a standstill. You can prevent this by pulling
out the parking brake switch as you press the accelerator (in the
same way as with a conventional handbrake).Emergency braking function
This feature enables you to stop the vehicle if the main
brake system should fail or if the pedal is obstructed.– Pull out and hold the parking brake switch to stop the
vehicle with the parking brake in an emergency.
– The brakes will be released immediately if you release the
switch or press down the accelerator.
If you pull out and hold the parking brake switch at a road speed
above about 8 km/h, this will initiate an emergency brake applica-
tion. The brakes are then applied hydraulically at all four wheels.
The effect is the same as an emergency stop (full brake application)
⇒
To prevent the emergency braking function from being used acci-
dentally, a warning buzzer sounds when the switch is operated. The
brakes are released immediately when you release the switch or
press down the accelerator.
WARNING
You should only use the emergency braking function in a real
emergency, for example if the brake system should fail or if the
brake pedal is obstructed. If you use the emergency braking func-
tion by activating the parking brake switch, the effect is similar to
a full brake application (emergency stop). Please remember that
the ESP (with its combined ABS, EDL and traction control func-
tions) is still subject to certain physical limits. In a corner or in bad
road or weather conditions an emergency stop can cause the
vehicle to skid or lose steering control.Driver messages in the instrument cluster displayCaution: Vehicle parked too steep
This message can appear when you apply the parking brake if the
car is parked on a gradient steeper than about 30%.
In this case the parking brake may not be strong enough to prevent
the vehicle from rolling back accidentally.
Please release parking brake
However, please remember that, for safety reasons, the parking
brake will only release automatically if the driver's seat belt is
buckled.

Driving 126The cruise control system allows you to drive at a constant speed of
30 km/h or higher.
A constant speed is maintained by adjusting the engine power or
braking the vehicle accordingly (while in cruise mode).
The cruise control system is set using the control lever ⇒page 125,
fig. 138. The indicator lamp lights up while the system is operating
⇒fig. 139.
The cruise control system is automatically deactivated immediately
when you press the brake pedal.
On vehicles with a manual gearbox, the cruise control system will be
deactivated if the clutch is pressed for a long time.
WARNING
•
Always direct your full attention to the road, even when you are
using the cruise control system. It is always you who is respon-
sible for determining your speed and for keeping a safe distance
to the other vehicles on the road.
•
For safety reasons, the cruise control system must not be used
in city traffic, stop-go traffic, roads with a lot of bends or in diffi-
cult driving conditions (such as ice, fog, loose grit or gravel, heavy
rain, aquaplaning) - this could cause an accident!
•
When you take a turn-off, drive along a motorway exit lane or
pass through roadwork sections, please temporarily switch off the
cruise control system.
•
Please make sure you do not unintentionally rest your foot on
the accelerator - this will override the cruise control system which,
as a result, will not brake the vehicle.Caution
On vehicles with a manual gearbox: do not move the gear lever into
neutral without depressing the clutch when the cruise control
system is active. Otherwise the engine could rev up and be
damaged.
Note
•
On vehicles with a manual gearbox, the set speed cannot be
reached if the currently selected gear is too high or too low. Change
down to a lower gear when the engine no longer runs “smoothly” or
change up a gear to avoid overrevving the engine.
•
The brake lights come on when the system brakes the vehicle.
